A couple of things wrong in this post.
1. You really think Pewdiepie cares about the 10s of dollars he would not be getting from his non existent Nintendo videos? He's just calling out Nintendo for doing something stupid. Many popular youtubers have done so. And if you actually heard what he said, you would know that he was generally speaking and not for himself.
2. MS and Sony are not cracking down on youtubers. As least not as hard as Nintendo. They know it's stupid(or at least I hope so). If you followed a few youtubers who had to deal with takedown notices and fought against them you would've seen how they all won in the end because they were in the right. Because their works are transformative, which is the basis for fair use.
3. A notice in front of every Nintendo video like that is a death sentence for any unbiased youtuber. It basically says: "I'm Nintendo's bitch but I'm still totally unbiased even though I'm not paying money to any other game developer out there".
4. This is not normal practice as I pointed out. Video games are an entirely different medium from music or film and as such shouldn't be treated the same way.
Last but not least, nobody is calling out Nintendo for doing something unlawful. It's just incredibly stupid. No one who even went against popular youtubers won in the end. All those hundreds of yens they will be making with this deal won't upset the massive negative publicity and even worse, the missing positive publicity.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
